- Example 1 Synthesis of sodium 2,5,8,11-tetraoxatridecane-13-oat (TEGM ECH2COQ-Na + )
- the crude 2,5,8,1-Tetraoxatridecan-13-acid is purified by double distillation in an oil diffusion pump vacuum (about 10 " 7 mbar, boiling point 135-145 ° C.) Finally, a colorless viscous liquid is obtained.
- the sodium salt of 2,5,8,1-Tetraoxatridecan-13-acid is obtained by reacting the acid with equimolar amounts of aqueous ⁇ , 1 M sodium hydroxide solution. After neutralization, the water is spun off. Drying of the product occurs successively in the oil pump, oil diffusion pump and turbomolecular pump vacuum (each several days).
- the compound sodium 2,5,8,11-tetraoxatridecane-13-oat can also be prepared non-aqueous by reacting equimolar amounts of 2,5,8,11-tetraoxatridecan-13-acid and sodium bicarbonate in ethanol. Drying is analogous to the aqueous synthesis.
- the polyether carboxylic acid can be titrated in aqueous solution with NaOH standard solution just to the equivalence point (via pH measurement). This method avoids inaccuracies in weighing the two components so that equimolarity is assured. The work-up is carried out as described above.
- 2,5,8,1-Tetraoxatridecane-13-acid is prepared as described in Example 1.

- the melting point is listed in Table 1.
- the viscosity of the ammonium salt is significantly lower than that of the sodium salt and is of the order of 20,000 mPas. It is comparable to the viscosity of honey or syrup. From electrical conductivity and fluorescence measurements it can be concluded that the ionic liquid according to Example 5 has a hydrotropic character in aqueous solution.
- the ionic liquid according to Example 6 has surfactant character. Due to the amphiphilic and therefore solubilizing properties, the ionic liquid according to Example 6 has a broader release spectrum compared to conventional ionic liquids. Furthermore, it can be concluded that the ionic liquid according to Example 6 has structuring properties in water, organic solvents and in particular also in the pure state. Accordingly, it can serve, for example, as a structurant (template) in mineralization processes (eg for mesoporous silicates). Furthermore, the ionic liquid from Example 6 is liquid at room temperature (melting point see Table 1).
- Example 10 n-hexadecylamine
- Example 1 n-octadecylamine
- the melting points, decomposition points and viscosities are listed in Table 1, respectively.
- Table 1 shows that the melting points of the ionic liquids increase with increasing chain length of the alkyl radical in the anion. By selecting the chain length so the melting point can be adjusted specifically. Likewise, the decomposition point and the viscosity can be influenced by the choice of the cation.
- Ammonium nitrate is highly soluble in TEGMECHbCOONa even at room temperature, currency rend NaCl in small concentrations at temperatures above 100 0 C dissolves.
- magnesium sulfate is appreciably soluble in TEGMECHbCOONa.
- Particularly noteworthy in terms of the environmental compatibility of the sodium salt is the solubility of olive oil up to ten percent by weight in TEGMECH2COONa.
